EOFException in Java

EOFException: 

java.io.EOFException

Signals that an end of file or end of the stream has been reached unexpectedly during input.

This exception is mainly used by data input streams to signal the end of the stream.

Note that many other input operations return a special value at end of the stream rather than throwing an exception.

Example: 

Java

import java.io.DataInputStream;
import java.io.EOFException;
import java.io.FileInputStream;
import java.io.IOException;

public class EOFExceptionExample {
    public static void main(String[] args) throws Exception {

        DataInputStream dis = 
       new DataInputStream(new FileInputStream("D:\\hello.txt"));
        while (true) {
            char ch;
            try {
                ch = dis.readChar();
                System.out.print(ch);
            } catch (EOFException e) {
                System.out.println("");
                System.out.println("End of file reached");
                break;
            } catch (IOException e) {
                System.out.println("IOException occurs");
            }
        }
        dis.close();
    }

}

Output:

Hello Java

End of file reached

Constructor of EOFException

Example 1:

java.io.EOFException.EOFException()

Constructs an EOFException with null as its error detail message.

Java

import java.io.EOFException;

public class EOFExceptionExample {
    public static void main(String[] args) throws Exception {

        EOFException eofException = new EOFException();
        System.out.println(eofException);

    }

}

Output:

java.io.EOFException

Example 2:

java.io.EOFException.EOFException(String s)

Constructs an EOFException with the specified detail message. The string s may later be retrieved by the java.lang.Throwable.getMessage method of class java.lang.Throwable.

Parameters:

1. s the detailed message.

Java

import java.io.EOFException;

public class EOFExceptionExample {
    public static void main(String[] args) throws Exception {

        EOFException eofException = new EOFException("hello");
        System.out.println(eofException);

    }

}

Output:

java.io.EOFException: hello
